1 de may. de 2024 · Heinrich Martin Weber (1842--1913) and Carl (also Karl) Gottfried Neumann (1832--1925) were German mathematicians. The Neumann function can be defined by a single expression: \[ N_{\nu} (x) = \frac{\cos \nu\pi \,J_{\nu} (x) - J_{-\nu} (x)}{\sin \nu\pi} , \]
Hace 4 días · The Bessel function of the second kind of order ν is defined as follows: Yν(x) = cos νπJν(x) −J−ν(x) sin νπ. Y ν ( x) = cos. ν π J ν ( x) − J − ν ( x) sin. ν π. This function is called either after Heinrich Martin Weber (1875--1913), who introduced Yν ( x) in 1873, or after Carl Neumann (1832--1925), with notation Nν ( x ).
